In the ebuild, there's a check for the JDK 1.5.x, causing it to fail: if (java-utils_is-vm-version-ge 1 5 0) ; then die "${P} cannot be compiled with a 1.5.x VM, set your system VM to a 1.4.x VM." fi This is no longer the case. Eclipse builds with JDK 1.5, and has done so for at least a few versions (in the 3.1 line anyway). I just did it myself (by making a new ebuild that removes that check). Reproducible: Always Steps to Reproduce:
I have tested this too with java 1.5 as the compiler.
Irrelevant stale bug.
